Used to get 280kms out of a tank now i get that with half a tank. Ok to the point, i knew there was nothing wrong with my fuel systems so looked for problems regarding air. And there i sure found it air flow was blocked with crap and oil ( don't ask how it got there 8( ). I replaced the air filter and what a difference! More power, more efficency. I think CHUBBZ, a formum member had a similar problem, well one thing to check out. No one ever suspects the air filter!Hope this helps to some of you!See ya!
i remember one of my mates put engine oil on his airfilter and it ran like the biggest ) felt like he had a parachute tied to the car lol 8-}
